Thaum nws los txog rau kev tshawb nrhiav cov lus tsa suab, muaj ob hom tseem ceeb: Microwave Sensors thiab Passive Infrared Motion Detectors.Ob leeg muaj lawv tus kheej cov txiaj ntsig thiab qhov tsis zoo, yog li qhov twg yog qhov zoo rau koj?Hauv tsab xov xwm no, peb yuav tham txog qhov sib txawv ntawm Microwave Sensors vs Passive Infrared Motion Detectors, yog li koj tuaj yeem txiav txim siab zoo tshaj plaws rau koj cov kev xav tau tshwj xeeb.

Cov ntsiab lus uas peb yuav tham txog:

• Lub suab sensor ua haujlwm li cas thiab lawv siv rau dab tsi?
• Dab tsi yog hom sensors sib txawv thiab lawv ua haujlwm li cas?

Dab tsi yog MOTION DETECTORS lossis Sensors siv rau?

Kev tshawb nrhiav kev txav yog ib feem tseem ceeb ntawm kev ruaj ntseg hauv tsev.Thaum cov sensors ntes cov lus tsa suab, lawv xa ib qho kev ceeb toom rau koj lub vaj huam sib luag tswj uas tom qab ntawd ceeb toom rau lub chaw saib xyuas thiab tejzaum nws sau cov xwm txheej tshwm sim thaum lub sijhawm ntawd nrog cov cuab yeej saib xyuas lub koob yees duab koj yuav muaj nyob rau hauv ib yam nkaus!

Motion sensors feem ntau siv rau:

• Thaum tus neeg nkag mus ze koj cov khoom lossis kev lag luam, koj tuaj yeem pom nws los ntawm kev saib xyuas koj cov suab thiab yees duab saib xyuas.
• Cov neeg tuaj yeem nkag mus rau qhov chaw txwv, yog li koj yuav ceeb toom yog tias lawv ua.Qhov no tej zaum yuav yog hauv qab daus los yog lub chaw nres tsheb hauv tsev.
• Txuag lub zog los ntawm kev siv lub teeb ci hauv ib cheeb tsam tsuas yog thaum xav tau.

YUAV UA LI CAS YUAV TSUM TAU TXAIS NTAWM SIJ HAWM thiab lawv ua haujlwm li cas?

Ob qhov kev siv ntau tshaj plaws yog Motion Detectors yog Microwave Sensors (MW) thiab Passive Infrared (PIR).

Microwave Sensor

Microwave Sensors yog dab tsi?Microwave Sensors (MW) yog cov cuab yeej siv los ntsuas thiab ntsuas qhov muaj qhov txav ntawm qhov chaw.Lawv ua hauj lwm los ntawm emitting microwaves mus rau hauv ib qho chaw thiab ces ntsuas lub reflected teeb liab.Yog tias muaj kev txav mus los hauv cheeb tsam, nws yuav ua rau lub teeb liab cuam tshuam hloov, uas tuaj yeem raug kuaj xyuas thiab ntsuas.

Microwave sensors yog qhov kev xaiv zoo tshaj plaws rau kev taug qab cov khoom txav, raws li lawv xa tawm microwaves thiab ntsuas qhov cuam tshuam ntawm lawv.Microwave thev naus laus zis tuaj yeem npog thaj tsam loj nrog lub zog me me thaum cov neeg taug qab infrared xav tau cov kua txiv hmab txiv ntoo kom ua haujlwm kom zoo uas ua rau nws muaj kev cuam tshuam rau hauv cov chaw muaj neeg coob lossis qhov chaw raug cuam tshuam txog hluav taws xob xws li laptop chargers nyob ze cov khoom siv hlau nkag mus rau hauv nws cov teeb liab.

Passive Infrared Sensors (PIR)

Dab tsi yog Passive Infrared Sensors?Passive Infrared Sensors, los yog PIR sensors, yog cov khoom siv uas ntes cov hluav taws xob infrared.Lawv feem ntau siv nyob rau hauv kev ruaj ntseg systems kom paub txog kev txav.PIR sensors ua haujlwm los ntawm kev txheeb xyuas cov cua kub tawm los ntawm cov khoom, uas yog vim li cas lawv feem ntau hu ua "heat-sensitive."Thaum ib qho khoom txav mus rau pem hauv ntej ntawm lub sensor, nws cuam tshuam qhov ntws ntawm infrared tawg thiab ua rau lub sensor qhib.

Lub passive infrared sensor yog qhov siv ntau tshaj plaws hauv cov cuab yeej kev ruaj ntseg hauv tsev.Infrared nthwv dej tuaj yeem kuaj xyuas qhov kub thiab txias thiab lub suab sensors siv lub peev xwm los txiav txim siab yog tias ib tug neeg lossis ib yam dab tsi tau dhau los ntawm lawv txoj hauv kev uas yuav ua rau lub tswb rau koj thaum nws tshwm sim;muaj txawm tias muaj ob hom sib txawv hauv txhua lub koob yees duab - ib qho pom ambient IR radiating los ntawm cov khoom tom qab zoo li phab ntsa thaum lwm qhov tsis yog qhov tshwm sim los ntawm kev txav ib leeg!

PIR sensors ua haujlwm los ntawm kev txheeb xyuas qhov hloov pauv ntawm qhov kub thiab txias uas tshwm sim thaum ib qho khoom txav mus rau hauv lossis tawm ntawm nws qhov chaw saib.Qhov kev hloov ntawm qhov kub thiab txias no yog tshwm sim los ntawm cov hluav taws xob infrared uas tawm los ntawm cov khoom.

Passive Infrared Sensors muaj kev ntseeg siab heev thaum siv nyob rau hauv qhov chaw qis lossis nruab nrab kub.Txawm li cas los xij, lawv tuaj yeem ua tsis tau nyob rau hauv qhov chaw kub kub.

Cov tshuab kev ruaj ntseg nrog cov lus tsa suab tsis yog hais txog kev muaj tswb thiab xuav ntau dua;lawv yog ib tug yuav tsum muaj.Lawv tsis yog tsuas yog ib qho ntxiv ntawm kev ruaj ntseg system, tab sis lawv tseem tsim nyog kiag li.Yuav tsis muaj txoj hauv kev los ntes cov neeg nkag tebchaws yam tsis muaj sensors.

Vam tias, peb tsab xov xwm tau qhia meej txog kev ua haujlwm ntawm cov lus tsa suab sensors hauv koj lub tsev kev ruaj ntseg, ntau yam thev naus laus zis siv hauv kev tshawb nrhiav cov lus tsa suab, thiab yuav ua li cas xaiv qhov zoo tshaj plaws, peb nyob ntawm no los qhia.
